Unusual presentation of Erdheim-Chester disease complicated by severe hypercalcemia in a 25-year-old male: initial assessment and follow-up with 18 F-fluorodeoxyglucose-positron emission tomography and 3 Tesla MR imaging

We present a newly diagnosed case of Erdheim-Chester disease in a patient who presented with influenza-like symptoms, and whose course was complicated with life-threatening hypercalcemia. The imaging features were characteristic, and diagnosis was confirmed with immunohistochemical staining. The FDG-PET-CT was useful in diagnosis and follow-up.

A giant retroperitoneal hemangiosarcoma in a young boy: CT findings

Retroperitoneal hemangiosarcoma (RH) is an uncommon neoplasm that derives from the vascular endothelium; due to its biological behavior, it should be distinguished from other retroperitoneal tumors. We report a case of a 40-year-old man with diagnosis of retroperitoneal mass, that was suspected to be malignant. The specimen was histopathologically proved to be a hemangiosarcoma. The patient was suffering from left upper quadrants prolonged abdominal pain, and had made a contrast-enhanced abdominal Computed Tomography (CT) that had shown the voluminous abdominal mass.

Endovascular Forceps Assisted Stuck Catheter Removal: A Case Report

Despite the high degree of safety associated with image-guided central venous access placement, the increasing use of long-term central venous access devices has brought greater attention to the chronic complications these patients encounter, particularly in the hemodialysis patient population. The rare occurrence of a stuck catheter can create a challenging situation in which the risk of removal and sometimes advanced techniques required must be weighed against the risk of infection and thrombosis associated with leaving the catheter in place. Removal of the stuck catheter through endovascular approach has been described by multiple techniques. The case presented is a successful stuck catheter removal through a novel technique by use of endovascular forceps following failure of other methods.

Key lesion localization and pre-surgical planning using magnetoencephalography in patients with medically refractory epilepsy: three case reports.

Epilepsy is a common and debilitating disease affecting up to 50 million people worldwide. Nearly 30% of patients with epilepsy have disease refractory to treatment with medication alone. Even in medically refractory disease, neurosurgical resection can be curative when the epileptic focus is correctly identified. Several non-invasive techniques are available for epileptic focus localization and pre-surgical planning. These include electroencephalography (EEG), magnetic resonance imaging (MRI), and magnetoencephalography (MEG).Each of these techniques provides complementary information for precise lesion localization and targeted neurosurgical approach to minimize damage to important adjacent structures. We present three cases of medically refractory epilepsy. The cases show how the combination of EEG, MRI, and MEG allows for lesion localization and safe surgical planning in a variety of cases. They include epilepsy related to cortical dysplasia, grey matter heterotopia, and tumor recurrence. We emphasize the role of MEG and demonstrate how it can provide critical additional information which is not captured by conventional EEG and MRI alone.
